The Franklin Arsenal tumbler is a popular choice for reloading enthusiasts, known for its robust construction and efficient cleaning capabilities. A common question among users, especially those new to reloading, centers around its capacity: How much brass can the small Franklin Arsenal tumbler actually handle? This article delves into that question, providing practical advice and considerations for maximizing your tumbler's efficiency and longevity.
Understanding the Small Franklin Arsenal Tumbler's Limitations
The "small" Franklin Arsenal tumbler, often referred to as the original or standard model, differs from the larger, commercial-grade versions. Its size directly impacts its brass-holding capacity. While Franklin Arsenal doesn't explicitly state a maximum brass weight, practical experience and user feedback suggest some important guidelines.
Case Capacity vs. Weight Capacity
It's crucial to distinguish between the number of cases the tumbler can hold and the weight of those cases. You can fit a significant number of smaller pistol calibers (like .223 or 9mm) compared to larger rifle calibers (.308 Win, .30-06). The weight of the brass, however, is the limiting factor. Overfilling leads to inefficient cleaning and potential damage to the tumbler's motor.
The Importance of Media-to-Brass Ratio
The ideal ratio of cleaning media (typically corncob or walnut media) to brass is key. Too little media results in poor cleaning, while too much hinders tumbling efficiency. A good rule of thumb is a 1:1 or slightly media-heavy ratio (e.g., 1.2:1 media to brass). This means, if you're using a pound of brass, aim for at least a pound of media, ideally a little more. Overfilling with brass and media will stress the motor and may lead to premature wear.
Practical Testing and User Experiences
Many reloaders have experimented to determine their small Franklin Arsenal tumbler's practical limits. Anecdotal evidence suggests that between 1 and 2 pounds of brass is a safe and efficient working range. Going significantly beyond 2 pounds often results in decreased cleaning effectiveness, increased noise, and potentially overheating of the motor.
Factors Influencing Brass Capacity
Several factors influence how much brass your small Franklin Arsenal tumbler can handle effectively:
- Brass Caliber and Size: Larger rifle casings weigh considerably more than smaller pistol casings, significantly impacting the overall weight you can safely tumble.
- Cleaning Media Type: Different media types have varying densities. Heavier media will fill the tumbler faster, reducing the amount of brass you can add.
- Media Condition: Old, worn-out media may pack down more tightly, leaving less room for brass. Regularly replacing your media is essential for optimal cleaning and tumbler longevity.
- Tumbler Condition: A well-maintained tumbler will run more efficiently than one with worn-out bearings or a weak motor.
Optimizing Your Tumbling Process
To maximize the efficiency and lifespan of your small Franklin Arsenal tumbler, consider these tips:
- Start Small: Begin with smaller batches of brass to gauge your tumbler's performance and find the optimal media-to-brass ratio.
- Monitor the Motor: Listen for unusual noises or overheating. If the motor sounds strained, reduce the amount of brass in the next batch.
- Regular Maintenance: Clean the tumbler regularly and lubricate moving parts as recommended by the manufacturer.
- Gradual Increase: Once you've established a safe working range, gradually increase the brass quantity, always monitoring for any signs of strain on the motor.
Conclusion: Finding the Sweet Spot
There's no single, definitive answer to "how much brass" the small Franklin Arsenal tumbler can handle. The optimal amount depends on several variables. By following the guidelines above, paying attention to your tumbler's performance, and starting with smaller batches, you can find the sweet spot that balances cleaning efficiency with the longevity of your equipment. Remember, prioritizing proper media-to-brass ratio and careful monitoring of your equipment will extend its lifespan and ensure reliable cleaning for years to come.
